This invention relates to valves in general and more especially toimprovements in combined hot and cold Water valves. Among the objects ofthe present invention, it is aimed to provide in a combined hot and coldwater valve an. improved control, whereby the main valve will beliberated from its valve seat preparatory to actuation to preventbinding, and thus positionedfor ready actuation.

It is also aimed to provide an improved volume control for a combinedhot and cold water valve of the character herev described which valvewill not require the use of springs and other yieldable material forforming aA yieldable seat.

In valves intended for use with mediums of varying temperature',numerous springs and yieldable means are generally used to preventbinding, and at the same time prevent leakage. lnthe presentconstruction, it is an object to use the least number of springs' andyieldable means, and in such a manner to arrange the several activeparts, that any leakage that may result between the several activeparts, will be so controlled that a pre-1 determined mixture canreadilybe obtained, and whereby -the outlets can simultaneously beeffectively shut off Without danger of any leakage.

Among other objects, the present invention also aims to produce a valveconstruction whereby a maximum etiiciency can be obtained with a minimumnumber of parts, and

5 which construction can be manufactured at a minimum cost, and bereadil assembled and installed by the average unskilled workman.

, These and other features, advantages and capabilities of the inventionwill appear from the subjoined detailed description of the .accompanyingdrawings, in which Figure 1 is 'an axial section of thevalve with partsthereof broken away.

Fig. 12 is a transverse section of the main housing showing the hollowspindle in place.

In the embodiment illustrated, there is shown a main casing 1, having anupper cylindricalv wall member 2, an intermediate of the main valvelcross-shaped- Wall member 3, and a lower cross-shaped wall member 4.The intermediate wall member 3 has a plurality of extensions, four inthe present'instance, that are formed in pairs substantiallydiametrically opposite to one another, one pair forming the nipples 5and 6 to serve as inlets, and the other pair continuing down into Athelower wall member'4 to form the nipples 7-and 8 which will serve asoutlets. Y

The bottom 9 of the casing forms with anular inner wall member 10 thechamber A for the valve. The wall 10 separates the mixing chamber A fromthe passages C and C', leading to the outlets 7 and'8 and extendsupwardlyto form the downwardly tapering wall member 13 which serves asthe valve seat for the main valve member. The Wall member 13 hasopenings 14 and 15 to establish communications between the nipples 5 and6 and the interior ofthe valve seat formed by the wall member 13.

Adjacent to the wall member 2 there is formed the annular platform 16,forming with the wall member 2, a closed upper outiow chamber B. Theplatform 16 has openings 17 and 18 formed therein'to commlini-V 10 thelower outflow chambers in communication with the nipples 7 and 8respectively.

The main valve member cooperating with the valve seat formed bythe ,wallmember 13 consists essentially of a casting 19, see Fig. 10, having anupper continuous annular rim 20, two depressions 21 and 22 at anglesrelative to one anotherA so as toxform an elongated face 23, and anarrow face 24 between them, the lower edges of the faces 23 and 24having rims 25 and 26 respectively .there formed. The rims 20, 25 and.26 primarly form abutments for the packing .member 27. The packingmember 27 as shown in Fig. 6 has two openings 28and 29L spaced from oneanother to conform to the spaces between the depressions 21 and 22 sothat such open` ings will register with the depressions 21 andV 22 `asshown in Fi 3. The packing member 27 is prefera ly formed of asuitable"J waterproof material, such as rubber, rubberized fabric or asuitably treated leather. The material of the packin member 27preferably also has suf' iclent elasticity so that when placed on thecastin 19, it will cling to the surfaces 23 and 24 an be anchoredagainst accidental displacement by the rims 25 and 26. The depressionsas shown in Fig. 3 are preferably covered with suitable metal plates28', 28- having upturned edges which edges 29', 29` form anchoringflanges with the rims 20, 25 and 26 to anchor the packing 27 againstLdisplacement relative to the casting 19, the plates being secured-inplace by screws or the like. The casting when equipped with the packing27 will t snugly in the valve seat formed by the wall member 13 as shownin 40 JFig. 1. The depressions 21 and 22 are positioned relative to oneanother as shown in Fig. 3 so that at the neutral, or closed position ofthe valve, the surfaces 24 and 23 will oppose the openings 14 and 15. Ifthe valve is turned counter-clockwisefrom such neutral position, it will"first open the opening 14 as shown in Fig. 3 and as this rotation iscontinued the opening 15 will also bc opened. Similarly, if the valve isturned in clockwisedirection, as soon as the open-` ing 14 is exposed,the water will be free to pass from the nipple 5 through the depression21 into the mixing chamber A, the water being barred from iiowingdirectly into the upper outflow chamber B by means of the rim 20 and theportion ofthe packing mem-- ber 27 adjacent to the rim 20. From themixing chamber A., the water is then caused to pass through theinterior` of the casting 19 to the vupper outlow chamber B. For normallymaintaining the main valve member in engagement with the wall member 13,the spring29 is provided. This spring is tensed between the annularshoulder portion v30 formed on the inner ends of the arms 31, 31

extending from' the interior faces of the cast- /ing 19, and the washer32closing the stufl'- ing box 33 formed in the lower` end of thechambered spindle 34.

The chambered'spindle 34 preferably has an enlargement. 35 at its lowerend to house the stuing box 33 and forms a shoulder 36 with the upperdiminished elongated portion 37 of the spindle 34 to receive the angedcollar 38 which closes the stuin'g box 39 formed-in the upper extension40 of the cover 41',`the collar 38 being secured in place against thecover 41 while' the spindle 34 is rotatably mounted insaid extension,stufling box 33 and collar 38 as shown in'Fig. 1 The stuiiing box 39aforesaid forms a watertight packing between the extension 40 and theelongated portion 37 of the spindle 34.

The cover member 41 as shown in Fig. 1 engages the upper annular edge ofthecylindrical wall member 2 to form the upper closure for the upperoutiow chamber B, a-suitable packing 42 being disposed between theopposing edges of the cover 41 and the wall member 2. The cover 41 andcasing 1 thus constitute the housing for the main valve parts.'

Through the chambered spindle 34, stuifing box 33, spring 29, andcasting 19, there extends the volume control rod 43, the packing 33forming a water-tight connection between the rod 43 and the spindle 34.The rod 43 terminatesin a diminished lower extension 44 which is spacedfrom the annular shoulder 30 of the casting 19 as shown in Fig. 1. Tothe lower end of the extension 44,

mensions than said opening 46, so that it may eii'ectually close theopening 46 in one position thereof (see the conformations of the opening46 and plate 45 illustrated in Fig. 5) and in turn as the plate 45 isrotated relative to the opening 46, it will expose the opening 46 agreater or less amount as desired. The plate 45 will be held in intimateengagement with the lower edge of the casting 19, and this is eected byadjustment of the manipulating knob 47. The upper end 49 of the rod 43is diminished and threaded, to receive the internally screw-threadedportion of the knob 47. In order to' lock the knob against rotation onsaid threaded end 49, a locking sleeve 50 extends into the chamberedportion 50 of the knob 47 and is screw-threadedly 1s preferablylprovided with a plate 51, onv

which there may be inscribed the notation Volume to indicate itsfunction to the user.

This plate 51 will also serve to give a finish to the upper end of theknob 47 and enclose p the sleeve 50.

The proper location of the knob 47'isl determined by the hub 52 of themain valve handle 53. This hub 52 rests on thehub 54 of the pointer 55which in turn rests on the dial 56, and the dial 56 in turn is securedto -the upper end of the upper extension 40 2v only partially 17 and18leading to the chambers C and C'.

In order to maintain the arcuate valve 57A in intimate engagement withthe valve seat formed by the platform 16 surrounding the openings 17 and18, the springs 58 and `59 are provided, anchored in place bythe pins 60and 61 extending up from the segment 57 and into the openings 62 and 63formed in the arms 64- and 6 5 respectively extending from theenlargement 35 of the spindle 34, the springs being tensed between thearms 64 and 65 and the segment 57. By means ot the pins 60` and 61 andtheir connection with the arms 64 and 65, the segment57 will be causedto rotate simultaneously with the rotation of the spindle 34. In orderto limit the amount oll rotation of the spindle 34 and also ofthe'segment 57; the arm 64 is provided with an arcuatestop member 66which cooperates with the stop 67 formed on the cove'r`41 and extendingdownwardly therefrom.

The connection of the handle 53 with the spindle 34 and its operationwill now be described. The hub 52 which is integral with the handle 53,is freely rotatable relative to the rod 43. The hub 54 of the pointer55,' however, is iixedly securedto the spindle 34, and consequentlywhatever rotation is transmitted to the hub 54 will be in turntransmitted to the spindle 34, and through the arms 64 and 65 to thesegment 57.

Due to the variation in temperature, unless provision were `made, themain valve embracing the casting 19 might so adhere to the valve seatformed in the wall member 13 as lto prevent the ready operation ofthesame. To guard agains such improper operation, the present inventioncontemplates means for positively liberating the valve from the valveseat before starting the rotative ac tion. To thisvend, the enlargement35 'of the spindle 34fis provided with two lugs 68 and 68', the lugshaving suliicient dimension to permit the pairs of lugs 69 and 70respectively of the casting 19 to slide axially, -but closes each of theopenings.

anchoring the. casting 19 against rotation rell ative to the spindle 34.The casting 19, thus forms with the enlargement 35 and spindle.

34a valve element in which these three constituent parts are rotatedtogether although the casting 19 may be axially movable relative totherenlargement 35. y

In order to actuate the cast-ing 19 axially relative to the spindle 34,and thus raise the main valve from its valve seat,/the hub 52 of thehandle 53 is provided with two cam lugs 71 and 72 which cooperate withthe camfaces 73 and 74 respectively of the hub 54 appurtenant to thepointer, 55. IConsequently as the handle 53, see Fig. 4, is actuated todraw water either for the bath or for the shower'the cam lugs 71 and 72will iirst ride up the cams 73 and 74 to raise the knob 47 andtherebyraisev the main valve from its valve seat, and then upon striking thesides 75 of the cam recesses: formed in the hub 54 will begin to rotatethe spindle 34 in turn to rotate the segment 57, and also rotate thelugs 67 and 68 in turn to-rotate the casting 19 of the main valve.

From the foregoing it will, therefore, appear that when it is desired todraw water for the bath,v the handle 53 is turned in a counter-clockwisedirection, whereupon the .cam lugs 71 and 72 first will cooperate withthe cam faces 73 and .74 to withdraw the casting. 19 of the main valveout of intimate engagement with the valve seat formed by the wall member13, and then upon the continued rotation of the' handle 53, will engagethe faces 75 ofthe hub 54 in turn torotate umv the spindle 34,,whereupon the depression 22, see Fig. 3, will register with the opening14 to permit the cold water, for instance, to enter from the nipple 5and then passV through the opening 14 andthe depression 22 to the mixingchamber A, and upon the further rotation of the handle 53, according tothe wishes of the user, the depression 21 will be caused to registerwith the opening 15', whereupon, for instance, the hot water will 4bepermitted to'enter from the nipple 6 and then pass through the opening15 and the depression 21 to the mixing chamber A: F rom the mixingchamber A, the water will pass up through the interior of the` casting19 to the upper outflow chamber B, and upon the opening 18 having beenfully uncovered, and the opening 17 entirely covered by the /arcus atevalve 57, the mixed water from the chamber A will be free to passthrough the lower outflow chamber C, to the nipple 8. If the water to bedrawn is to be used for the shower, the handle 53 will'merely be turnedin the opposite direction, and. the water caused to passthrough theother set of corresponding openings to the nipple 7. The position of thevolume control valve or plate 45 relative to the opening 46 isdetermined by the position of the knob 47 and will con.

trol the volume of water to be drawn.

It is obvious that various changes and modifications'may be made to thedetails of construction withoutdeparting from the general spirit of theinvention lset forth in the appended claims.

It is also, ofcourse, obvious that fluids other than water may be usedwith this valve, and that the reference to hot and cold water lis merelyin explanation of one use :tor the valve constituting the ypresentinvention.
